Everyone is used to the "Sign in with Google" and "Sign in with Facebook" buttons. Almost any service suggests using those when you register as a new customer. The "Sign in with Apple" can be used just like the two above.

Sign in with Apple is an easy and quick way to log in to any of your Apple devices running on iOS/iPadOS, as well as Mac, Apple TV, and Apple Watch. 

Moreover, it works in any browser, which means you can use it on your website and in versions of your apps running on other platforms.

Did you know? All accounts are protected with two-factor authentication for superior security, and Apple will not track users’ activity in your app or website.

Do not hesitate to try it out on any of your Apple supported devices.
